GEORGE B. HART, OF ROCHESTER, NEVI YORK.

COMBINED TACK AND STAPLE.

To all whom it may concern Be it known that I, GEORGE B. HART, a citizen of the United States, and a resident of Rochester, in the county of Monroe and State of New York, have invented a new and Improved Combined Tack and Staple, of which the following is a specification.

This invention relates to means for readily and removably securing light bodies together so as to lie in the same plane or in planes disposed angularly relatively to each other.

The object of my invention is to provide a device of the character described which is adapted to connect the parts together in the manner above indicated and, so far as possible, irrespective of the angular disposition of the parts or their relative arrangement; and a device, also, which may be used in attaching such parts together whether of the same or different material such as cardboard, press-board, corrugatechboard, fiberboard or wood. I

A combined tack and staple in accordance with my invention comprises, preferably, two prong members separated throughout their entire length and pointed to facilitate their insertion in card-board or press-board, and adapted to be folded down thereagainst on the side opposite that from which they are inserted. Such a combined tack and staple comprises the combination with prongs, of such above indicated conformation, of a head to which the prongs are attached, and preferably, though not necessarily, formed integrally therewith.

The head member which, as above indicated, may be formed integrally with the prongs is, preferably, of disk like conformation with teeth or points extending at rightangles with the plane of the disk and adapted to engage into and in some cases through the body to which the staple is to be attached. When the head is attached to a body the prongs, whether integrally formed there with or not, are held firmly clamped to the body against which the head is attached.

I have sometimes found it desirable to make use of a reinforcing tack engaging through the head for holding the head in place. For this reason the head is preferably provided with an opening for receiving the tack.

In the accompanying drawings I have shown an embodiment of my invention in which the prongs and head are integrally Specification of Letters Patent.

formed, without, however, limiting myself to such integral formation. Such drawings are as follows:

Figure 1 shows a plan or top view of the device. Fig. 2 is a side view, and Fig. 3 a central sectional view taken along the line of division between the prongs. Fig. at shows one of the methods of using my combined tacks and staples in the formation of a bracket from corrugated board in which a bracing member is used, which may be formed of wood. Fig. 5 is a partial view from the right of the parts seen in Fig. 4:.

Similar parts are designated by similar reference characters throughout the several figures ofthe drawings.

Referring to the drawings,At P is seen the head of the tack portion provided with, and having integrally formed therewith, teeth t extending at right angles with the plane of the head R The head P is conformed by means of suitable dies, as indicated in the drawings, to provide a ring-like ridge 7", the outer periphery thereof extending downwardly into the teeth 25. Within this ring-like ridge 1 there is seen a depressed portion 0 within which latter there is formed araised portion 6 through which an opening 0 is seen for receiving an attaching tack when needed.

Prong members "0 may, preferably, be conformed as indicated in the drawings and preferably also, although not necessarily,

integrally formed with the head, the essen-' tial feature, however, being that the prongs are operatively held and attached to any suitable body by means of the attachment to the body of the head P.

Refer now to Fig. 4 in which there is seen a bracket shelf such as may be constructed from corrugated board for receiving any small and light objects. Such a bracket may be readily formed from card or press board whether corrugated or not, by the use of my combined tacks and staples. B is the back of the bracket and T the shelf attached thereto by means of one or more of my tacks or staples, preferably at least two. The teeth t on the head P are inserted through the shelf T near its rear edge and the ends if projecting therethrough are bent downwardly thereover. The prongs o are inserted through suitable slits therefor, which may be previously made or which may usually be made by the prongs themselves as they are pushed through the back piece B, and the projecting ends of the prongs a: of each tack and staple are bent,

one upwardly and the other downwardly,

and forced against the rear side of the back piece B. For supporting the outer edge of the shelf member T a bracket of wood, such as seen at D, may be made use of. The upper end of the bracket D is beveled, as indicated, and the head P of a combined tack and staple is secured thereto and a tack may be made use of formore firmly attaching, when necessary, the head P against and to the upper end of the bracket D and with the teeth t engaging into the end of the bracket bar D. The prongs o of such a tack and staple are bent downwardly one, preferably, inwardly and the other outwardly, as seen in Fig. 4, on the top of the shelf T. In the same way the lower end of the bracket member D is attached to the wall piece B of the bracket shelf. The back B of the bracket shelf and the shelf itself T are seen as formed of corrugated board, the upper and lower layers of which are seen at awhile thefcorrugated intermediate layer is seen at When the article or body to which the head is attached is thin enough to permit it, the tips of the teeth t may be clenched against the surface of the body through which they engage and, when such article or body is formed of corrugated board or like material, the ends of the teeth will thus be embedded into and not show above the surface of the body or article.

My combined tacks and staples may be made in sizes suitable to the use to which they are to be put.

From the foregoing description of my combined tack and staple it is believed that the adaptation of the same to various uses and the method of using the same is sufficiently clear to call for no further explanation herein.

What I claim is:

A device of the character described comprising independently flexible prongs adapted to be inserted through and bent down upon the opposite or rear side of the body to which the device is to be attached and a head lying normally in a plane parallel with the prongs, the head provided with teeth ex tending substantially at right angles with the plane thereof and adapted to engage into the body to which the head is to be attached, the head operating to hold the prongs in attachment with the body to which the head is attached.
